So let’s break down a typical Disney wedding budget:
Ceremony fee: $3,500
Wedding pavilion with organist: $4,000+
50 dinner guests at $175 each: $8,750
Plus 23% service charge and 6.5% sales tax: $2,581
Charter bus transportation (required for five hours): $551
Minimal flowers: $948
DJ (four hours): $1,650
Photographer (four hours): $2,995
That means — not counting the dress or rings — you’re looking at nearly $25,000 for the bare minimum required by most couples.
Disney Weddings Come With Extras… and Extra Costs
But what if you want any fun stuff? I mean, come on, it’s a Disney wedding.
Here’s how much some of those extras would set you back:
Arrival in Cinderella’s coach (complete with miniature white ponies and costumed footmen): $2,950
Appearance of two characters for 30 minutes: $1,650
“Memories Video Package”: $4,550+
Live band: $7,000+
You can check the a-la-carte offerings on this site, but note: “Prices do not include any applicable tax, gratuity or additional fees.”

I worked with a guy who offered his daughter a deal. A small backyard wedding and he would put $30,000
down on the house of her choice. This is back when nice houses were $70/$80 grand.
